1 CARSON CITY PURCHASING AND CONTRACTS 201 North Carson Street, Suite 3 Carson City, NV /FAX NOTICE TO CONTRACTORS BID # Sodium Hypochlorite Tank Replacement Project PWP # CC Addendum No. 1 Please make the following additions/changes/clarifications to the above referenced project: 1. On sheet C6 of the plans the water supply line (by others) is not within the scope of the project and will be installed by the City. The Contractor s will be responsible to install the check valve and everything on the building side of the valve including the utility box as shown on the plans. 2. There is a conflict between detail 1 sheet C8 of the plans and detail B sheet E2 regarding the tank level display. The contractor is to relocate the existing tank display pedestal as shown on sheet E2 rather than supporting the tank level display with preformed channel as shown on C8. 3. The NaClO tanks shall be labeled Tank A (tank to the west) and tank B (tank to the east). Please use these labels rather than the labels referred to on note 8 on sheet E3. 4. Information on the fire alarm and sprinkler system has been provided at the back of this addendum. A complete set of shop drawings it to be submitted and approved by the Carson City Fire Department. The fire alarm system and plumbing shall be included to the list of required submittals noted in the Special Conditions of the bid document. The fire sprinkler system will not need additional corrosion protection beyond what is typically provided excluding where the riser penetrates the containment floor as shown on the attached Fire Riser Location and #3 Water Plan. 5. A drawings showing more details on the tank connections and location has been provided for your reference. The following is based on questions received prior to October 2 nd, 2014: 6. DEMO-west wall-is contractor to abandon in place existing pipe conduits for cl2 service / water system. Method of abandonment.

2 The existing pumps and piping shown on the west side of the NaClO tanks on sheet C3 are to be removed and disposed of except for the 2 #3 water line. The 2 #3 water line is to be relocated 30 above finish floor where it currently penetrates the slab. The existing hose bib may be reused and the drip line to the swamp cooler reconnected. All abandoned pipe conduits within the limits of the new containment basin are to be removed and the conduits capped where they continue beyond the new containment basin limits. 7. The contract time of 48 working days does not work and will not allow for procurement of the longer lead items such as tanks and pumps. The procurement time for these items will be submittals 3 weeks, approval estimated at 3 weeks, fabrication 6 weeks, delivery 3 days for a total of weeks. Can the contract time be extended by 2-3 months or can the notice to proceed be delayed until the procurement of the long lead items is complete? The start of the construction period will begin with consideration of long lead times for items. 8. CA. 12 Requires all submittal to be submitted within 15 calendar days of the Notice to Proceed with $250.00/cd damages for late submittals. As per item 1 above we are hearing submittals will take 3 weeks can this time be extended or the NTP delayed to allow for submittal/procurement? The City will work with the Contractor to determine a Notice to Proceed date in consideration of lead time items and their submittals. 9. GC 7.13 By-Pass Pumping of Sanitary Sewer. I did not see where bypass pumping would be required on this project. Please confirm that this section does not apply and that there is not bypass pumping required. No by-pass pumping will be required for this project 10. Regarding the existing PLC program that is within the Allen Bradley SLC 500. The project calls for a new Schneider Electric M340 PLC to replace the existing SLC 500. In order to determine a more accurate budgetary estimate of time and cost to perform the migration, can a copy of the existing PLC program be made available? Regarding the existing I/O modules and the hard wiring to the modules. It appears there is more I/O than indicated on sheet E5 of the electrical drawings. Is there a more detailed I/O drawing that can be made available for the bidding process? It is the City s intention that the PLC program be migrated using Schneider Electric software conversion tools as shown under step one of the Rockwell Migration Brochure included in this addendum. Additionally the hardware migration shall be performed using the Schneider quick wiring adapters as shown under step two of the attached brochure. A copy of the existing program is not being provided during the bid process. By utilizing the conversion software and adapter hardware available from Schneider the new PLC programming

3 efforts should be limited to QA/QC of the migration and the new I/O and controls as shown in the bid set. 11. Shall the sump pit and sump pit walls be wet cured as called out in the notes of sheet C5? Yes, all concrete within the containment basin shall be wet cured as called out in the plans. 12. Plan sheet C6 references building ventilation requirements and existing equipment. Are we to assume this is for reference only and not a requirement to install new equipment? Yes, no new ventilation equipment will need to be installed.

23 Better plant performance begins with an efficient control system Migrate your legacy Rockwell PLC to a Unity-based Modicon control platform for a complete state-of-the art solution

24 The risks of an ageing control system As industrial systems around the world get older, a significant number are nearing the end of their useful life, like the Rockwell SLC500. Updating your aged installations with the latest technology now will help you retain your productivity and competitive edge by avoiding: Unscheduled downtime Expensive repairs and long lead times for spare parts Inability to support new information technologies Unreliable electronics Diminishing productivity Limited network options and restricted openness

25 Modernize your control system now and maximize uptime and production Modernizing your control system is much more than just a technological upgrade. It is your first step on the path toward innovative industrial process management that also optimizes your existing investment. When modernizing your control system, you need a partner with experience, someone who understands the specifics of your industry and can unlock the opportunities to expansion and competitiveness and very importantly someone who has the global resources to support you with: Open, integrated and scalable automation architectures Global support and solid execution capabilities Complete service capabilities to support you throughout the entire lifecycle of your system In-depth knowledge of your industry and a large network of partners to help build a complete solution Improved energy efficiency Unscheduled downtime costs on average 5% of the value of total production.
